Permiso denegado (clave pública) en Amazon EC2

Aquí está mi problema.

  1. I created a new instance, use the same key pair of another instance.

  2. SSH to the new instance, running ok.

  3. I terminate the old instance.

And when I SSH to my new instance with the key, it got problem.

OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011

So I checked other answers, maybe I should create a new instance and mount this one to add public keys. Is this the only way to solve the problem?

Gracias por ayudar.

Please note that instances are independent of each other. If you are implying that new instance got corrupted because you killed older one. It's probably a wrong direction to think of. -

Thanks, I mean the way provided herehttp://alestic.com/2011/02/ec2-fix-ebs-root. Maybe I create a new one and setup the environment will be more quickly. -

Yeah, just fireup a new instance. Looks like you lost access to this one anyway. -

Not sure if you got it sorted or not but permissions on your private key may give that error without any further specification. I´m aware that you in this specific case probably didn´t change the file permissions though.

However, if thats the case, just sudo chmod 600 ~/.ssh/your_private_key Especially putty in windows enviroments seems to just deny access, linux usually tells you to change the permission.
